Interestingly, the Insurance Institute for Highway Safety (IIHS) doesn't seem to think headlight glare is a problem [0], as unconformable as it may seem. I suspect there may be a selection bias at play here though. They also conclude brighter = safer. Part of me wonders if the glare also forces drivers to go slower, counterintuitively leading to safer driving.

Anyway, either way, it sucks. Some of the headlight glare is so bad now that I'll see afterimage streaks from headlights even during daylight hours!
